Same thing happened to mine! I was just closing the trimmer as usual when I was done using it and I heard a clicking or snapping sound and now it doesn't properly close all the way and stays out a little! Did you have a similar experience or did it happen over time?

​@@M1sterFancyPants Mine did the exact same thing as yours. A click and now a flappy trimmer door :) I've been using Braun razors for 30+ years and love them. What galls me is the last time this happened a number of years ago on a previous razor (had no idea how to fix it), I took it to a Braun dealer and got charged $85 to fix it. Apparently, all he did was take it apart (probably way less than this video and reset the spring) grrrr Anyhoo, I am going to break mine down and see if it's just the spring popped out. Great video, right? :)

Thanks for sharing and your feedback!

thanks for your additional input. when you are making a video you forget some things, some seems obvious, but are of course not obvious to everyone and it's impossible to correct it afterwards.. that's why I really like comments like yours that explain some points that I have missed. Glad you found this information useful and gave a try at DIY! nice job!

Quick follow up question? I purchased Braun Series 7 Cassette 70S (9000 Series) (Basically replacement blades) and was wondering, theirs gotta be a way to sharpen/or send out to get sharpened my old Braun blades. Please Braun Series 7 people/customers/professional Braun Employees/Engineers , this is such an amazing product , please incorporate a blade sharping business that goes along w/ the sell of the new Cassette! You guys figure that out , literally any he best product ever made!

Not a Braun representative but I assume that mesh of the casete get holes not long after the blade gets dull..

Glad it helped! And thumbs up for Braun - for a serviceable shaver :) nice to see not soldered batteries and glued in housings :)

@@letsfixitgarage What type and capacity battery is req'd?

Sorry don't have exact measurements but it is quite specific Braun battery it even has these pins on both ends for easy inserting and removal so you should look for a battery for your specific model..

I've had my 790cc for over 8 years now, used alternatingly with a Norelco triple head shaver (to give shavers a break from the rigors of daily use). At one point, I misplaced mine and the battery ran down to deep discharge. But it charged right back up and still holds a decent charge level. Braun used quality batteries in these units.

Good job 👍 one more unit saved from the electronic land fill. These expensive electronic devices are build to last we just need to share the knowledge!

these are quite reliable and powerful shavers! even s9 fails behind with reliability.. glad it was helpful and thanks for the beer ;) hope you will succeed with ambitious project ;) in that case you would have a working spare for quick exchange.

Nice work, yes sometimes at disassembly some of the cooper legs could get bend so do check that you have good contact when assembling and if it doesn't work, or charge, these legs would be the first suspect ;)

Thanks for a good word! spread the knowledge :)

:)) my intention was opposite, to show that it's doable.. but saved time is value as well :))

Actually, if your trimmer suffered some damage that is not reparable, you can buy the part for $25 USD off of Amazon. It doesn't look that hard to replace. In fact, it looks like it may be possible to detach the trimmer from the body without disassembling anything else.

Thanks for a good word ;) if possible share the knowledge!

Good to hear :) and thanks for the feedback!

Nice job! Hope grandpa is proud and happy ;)

Thanks for your Feedback!

Thanks for a good word ;)

Just wanted to add that "beloved" is a good way to put it. The 7-series is a terrific design. I've seen the newer models and frankly, Braun didn't make any real notable improvements. They just keep changing the styling and maybe some tweaks to how the motor works. But frankly, this shaver is a top design as-is. I was a long time user of the previous model the 360 complete 8900 series, which was a terrific shaver for its time. But the body is a little slippery to hold and the motor is a little weak. The 7-series helped reveal those flaws by providing a super strong motor and phenomenally grippy rubber backing. I think I'll end up buried with mine when my time comes. LOL!

It is a really good design with head fixing it's even better then series 9 that has its infamous loud noise where plastic head is fixed with metal arms and plastic wears out.

@@letsfixitgarage Good to know this. I had been toying with the idea of picking up a used Series-9 to play around with it, fix minor problems, etc... but sounds like it's not worth bothering about. Btw, one good indicator of abuse to a Braun shaver is the bubbling or erosion of the outer coating (e.g. silver, black) along the back edge just below the shaver head. This usually means the owner dumped alcohol into the cleaning solution to try saving money. That alcohol can cause degradation of parts, not just cosmetic but also mechanical.

Not sure about this as original cartridges contain a lot of alcohol as well.. so even with original cartridges you will get this problems if you will use the cleaning station like after every shave.. this is the weak part of series 7. I believe there are some black series 7 that don't have any coating on the frame these don't get the problems in cleaning station, but silver or glossy surfaces tend to peel..

@@letsfixitgarage Good to know. Yeah, I think the main reason why I don't see it happening to my shaver is the infrequent cleaning station use. I run it about once a month or two, and perform manual cleaning in between. I replace my cleaning station cartridge about once every other year!

For cleaning compressed air is a good option. cleanes out all kind of hair much better then the cleaning station! But do it outside ;)

@@letsfixitgarage For the most part, I just use a good cleaning brush. I also wiggle the head back & forth without the cassette installed first, as well as rap the cassette against the inner wall of the sink. and follow with a brush. And occasionally, I'll run a jet of water over and through the cassette for general cleaning. About once every other month, I'll use the Braun cleaning station so I fully refresh the shaver. I always clear out the whisker debris first, which significantly extends the life of the cleaning fluid. I replace it about once every two years.

Thank's for your suggestion! When you have all kind of tools at your hand its not a first thing that comes to your mind... I will try to remember it next time.

Yes sorry about that, audio is improved in later videos, but with the staying in shot it's more difficult then it seems :)) thanks for the feedback!

i dont mean to be so off topic but does anyone know of a method to log back into an Instagram account? I somehow forgot my login password. I love any tips you can give me

@Colby Timothy Instablaster :)

@Jabari Ulises thanks for your reply. I found the site on google and I'm in the hacking process atm. Seems to take a while so I will get back to you later with my results.

@Jabari Ulises it worked and I finally got access to my account again. Im so happy:D Thanks so much, you saved my account !

@Colby Timothy glad I could help :)

Glad it helped and thanks for taking time to give feedback :)

You're right the plastic is quite soft and you need to be carefull in not to overtighten. The rubber seal will take care of waterproofnes so stay calm ;)

Great! thanks for sharing :)

Freut mich zu hören :)

My suggestion would be to take out the cartridge out after cleaning. Solution is alcohol based and has a lot of evaporation that comes right up to the shaver.. normal water humidity shouldn't be a problem for them..

Really appreciate it, Thank you!

Glad it was helpful 👍

Need to look if I have some of the old parts. I do remember that there is a small plastic hook, that if broken, spring tends to jump out of its place...

Thanks for the feedback and your welcome ;)

Glad you enjoyed it!

I saw series 9 head reassemble video on KZfaq not sure if series 7 is here as well..

Thanks! and for subtitles thank you Google ;)

Yes thanks for pointing it out. I found it after I made the video. I think I added some text in to the video that this part was forgotten but I'm not to sure.. maybe it was left out...

Thanks for the feedback. And hope that it's only jumped out spring and not broken part. Although even if some plastic comes off it's still possible to fix it in place with some hot glue.. good luck and hope it works out!

@@letsfixitgarage You're welcome. Actually, my issue was a little more complex. The plastic fuse-tabs that hold the silver part to the switch panel (it sticks through with those curved bits of different sizes) had somehow deteriorated and broken up. This loosened the switch enough so that one of the spring ends slipped out of the retainer and then the trimmer wouldn't lay flat. When I took my shaver apart, that sliding switch panel completely came apart. I was then lost about how to put in that lever and spring. I had to freeze frame your video a few times to finally figure it out. The first trick was realizing the orientation of the lever. I could see one end was like a raised plug, where it looked like a spring would attach. After getting the orientation tested, I applied several dollops of epoxy glue at the 4 adhesion points, inserted the lever into the silver part, then lowered the silver part into the switch panel. After it dried, I was able to attach the spring. One tricky thing--there's a little magnet that's essential! Mine fell out. I figured out where to put it before lowering the silver part into place. I got the rest of the switch into place, anchored the spring ends, and now the switch is working properly. I was going to wait until tomorrow to finish assembly, but I decided to give it a shot, and it went smoother & faster than I expected--all working great! Thanks again for your video help.

sadly to much thin plastic.. trimmer frame could really be from metal then again to reliable is not what manufacturers want in this time..

Yes, if the components made from metal or more solid material would be much better, But to be honest, I found part of the plastic trimmer broken. But after reassemble the trimmer, it worked perfectly! 😀

@@letsfixitgarage absolutely right

Thanks for the hint. I think it's comon on series 9 maybe they changed the design on some of series 7 as well

Sorry haven't tried to take the head apart.. only on series 9 and haven't managed to get it back together... Very delicate work... After that haven't tried to get in to series 7 head :)

Check how you inserted the control board or maybe you have bent the metal legs.. it should touch the motor unit.

Nice catch :) yes, you are right, after filming it and cleaning up I saw it laying there, had to disassemble it one more time to insert it in to the turn on button.

Yes spare parts are unreasonably expensive compared to new unit price.. although you need to take in to account warehouses and so on.. difficult to judge, but manufacturers do love new consumers more than selling spares that's for sure.. you can look in eBay for a spare unit.. but this trimmer is a week point of this shaver..

It's already some time when I repaired these need to get one on my hands to make a video :) but if I remember correctly sometimes some plastic holder/leg brakes off that's why it doesn't hold..

Sorry haven't tried to take the head apart. At least on series 9 there are a lot of springs that are a pain in the a** to put back together.. my suggestion would be either look for a used or broken series 7 shaver and Exchange the head or of course there is possibility to contact Braun and get a new head.

Did you disassembled it up to motherboard and battery? It could be that you have bend some of the metal pins of the casing as its just pressing in.. check it one more time..

I have seen videos on KZfaq on how someone takes them apart and reassembles them.. sorry don't have them on hand but they are there... a lot of very delicate work..

Trimmer or shaving head? Trimmer is done in this video, shaving head lays on my table disassembled I think it needs some special tools to assemble it..

Trimmer! You take it out, but you do not completely take it apart. You even mention that it would have to be glued if taken apart. Thank you very much

@@davidgove1999 needed to check the video as I already forgot how it was done :) yes I haven't shown step by step how to take it apart but you can get the steps of the trimmer assembly from roughly 8 minute.. it's always easier to take things apart as to assemble it back together :)) and if yours falen apart and not only closing it could be some plastic parts on the frame.. then only exchange of trimmer can help as there is no spare part as frame only..

Well you will need to open it up, as in this video, and inspect the internals. there is no magic cure for something not working ;)

Check both trimers when they are disassembled side by side. There is small plastic part that holds the spring in place and it can be that one of the plastic bits is broken off that's why it's not holding in place.. you need to recreate the plastic holder with hot glue or something else..

@@letsfixitgarage Thanks, good idea about comparing the two. I didn't see any apparent broken pieces, but perhaps the problematic one might have some plastic erosion that's allowing slippage. I'll give it a go with some glue and if that doesn't do it, I'll have to source a new part. I'll post results later -- cheers!

@@letsfixitgarage OK, my first attempt failed. I used "Super Glue" but that didn't work for this application (it cracked). Instead I used Shoe Goo. It dries firm, but is still slightly flexible. It provides just enough staying power to keep the spring peg from slipping out. Of course, from here on out, I'll be very gentle and slow with moving the trimmer, but so far, extending/retracting a dozen times... seems to be holding.

To add, as you’re reassembling it, your hands move off camera, and I haven’t yet figured out how the trimmer is locked in place. About 10:40

@@ReTracer thanks for your questions. It was quite dirty to dissassemble it on camera.. maybe I should refilm only that part on close up.. in principle at 10.40 you just slide in the trimmer blade in to it's housing.. and why I took it of camera, is because you need to align the leaver in to it's place on the blade and at that angle it is impossible to see where it's going.. aside from that it's just sliding in.. and rest of the disassembly is just the reverse of the assembly on the camera, after you disengage the springs it will be very easy to get it in parts..

As far as I can remember power button just sticks on top of the casing so it shouldn't be affected by water. just check out this video one more time.. especially the assembly sequence, main task is to keep water away from electronics..

Water inside or behind the button should-not-hapen. After 8 months of use brown rustwater emerged from my Braun. The trimmer got rustspots all over. It was repeared under warranty by replacing the body. No water behind the power button anymore!

Good idea, will do!

Sorry no idea.. I usually get my things at eBay but haven't seen there new parts. Maybe try to contact official distributor service department. Sometimes they can help with parts as well.

Could be that plastic clip is damaged/broken try to add UV glue or epoxy to make better holding point for the spring

@@letsfixitgarage Thanks, I bent the ends of the springs toward each other and now they stay in perfect

I think I mentione that it's possible to disassembly it but I was not successful in assembly :) so do it at your own risk, but then again I saw few videos where it was done so it is possible.

@@letsfixitgarageYep, springs(all under load) and a bunch of small parts that tediously need to be put back together. It sucks.

@@Astromyxin exactly.. I'm not patient enough for that :))

Well I solved it, they neded to be under extreme tension to put back in. The only problem is now the springs from the release button are rubbing on the hinge when it moves so I'm not sure what I did wrong. There is a real lack of documentation on this stuff.

I only disassembled series 9 head once and sadly after that it was impossible to get it back together.. it seams that you need some special tools to have all the springs under compression and be able to assemble it.. so I have it in a plastic bag maybe in some time a solution will come up but for now disassembly of head is a big no no for me :)

PTFE spray if I'm not mistaken.

When you open the case the battery simply pushes out of holding clips. But replacement battery needs to be exactly for this model as it has some special tips spot welded to it..

It's ptfe spray or teflon spray, it's not as messy as regular oil. I think i bought it from lidl, haven't used a lot of these - so no brand recommendation for now ;)

Simple pull out. When you get to the pcb you just pull it out. Ofcourse the battery that you buy needs to have these special pins on both sides..

@@letsfixitgarage Do you know where I can get the battery at? Thanks for your help and reply. Just subbed.

Not sure where you live but there are plenty on ebay or other specialized servicing sites. Even aliexpress has them :)

@@letsfixitgarage Yes Found it on eBay. Thanks alot. Loos pretty easy. 👊

I tried only with series 9 and failed to reassemble it.. but I have seen videos on KZfaq of someone doing it. So it's possible but extremely difficult and time consuming.. don't recommend, especially only for cleaning..

Send me a photo or a link to the photo.. there is a lot of screen modifications on the 7 series..

Bought it from china, try to google wowstick it's quite handy and quality is up to the price i really like it :)

I was about to ask the same thing.

Sadly no.. my source is eBay :)

@@letsfixitgarage found one in UK online store. And will rewatch your video soon, when iy will come to install the new trimmer part. Cheers :)

That's quite some time ago, sorry but I don't remember and if I'm not mistaken it's torx screw's not hex..

@@letsfixitgarage Ok thanks. I'll figure it out but that helps.

sorry about that. it's an old video, some improvement are there but I'm still learning from bigger channels and their quality..

Yes you are right! Needed to re do it off camera when I spotted the mistake.

this particular electric scredriver came from china :) aliexpress has lots of suppliers with this screwdriver. Quite handy, altough you press the buttons quite often unintentionally when you want to use it as normal screwdriver..

Torx Number 8 is the one

I'm a private diy'selfer so no secret supplies :( aliexpress and ebay is where i look for spares..

Sorry, no idea.. haven't used any spare parts service, just eBay with additional series 7 for spares..
